Tub molding

I had a new tub placed, and it seems like they cut the linolium floor too much, they tried to use chaulking to hold the floor in place against the tub, but it's been three months and the edge is starting to rise.

I had the floor guy come in to look, and he said that I could try a pice of quarter round painted white to solve my problem.

The problem now is that my tub base is not entirely straight. It curves towards the tub at the ends approx. 1 3/4 at both ends curves.
